partitioning

[dustin kempter]

Hi all, I am an SA in training and ive been reading a lot about the 
importance of separating out your workspace/server into separate 
partitions such as /, /data, /home, /ftp, /usr, /boot vs dividing it 
into just a /, /boot, /data. and it seems that doing it how Ive been 
reading about with more partitions is more secure but what about when 
one partition becomes full? isnt that more of a problem vs one big /data 
partition where that is not an issue? what would you guys say the best 
solution would be? also read that you want to have twice as much swap as 
RAM and that dividing swap into 2 partitions helps with performance. is 
this true?

thanks
